Improvement in spring bed-bottoms



UNITED STATES PATENT OFFICE,

ALEXANDER OOLE, OF LOOKPORT, NEW YORK.

IMPROVEMENT IN SPRING BEvD-BOTTOMS.

Specilieation forming part of Letters Patent No. 56.373, dated July 17, 1866.

To all whom it may concern: 1

Be it known that I, ALEXANDER COLE, of Lockport, in the county of Niagara and State of 'N ew York, have invented a certain new and useful Improvement in Bed-Bottoms; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, in which- Figure l is a perspective view of an ordinary bedstead with my improved bottom. Fig. 2 is a cross-section of the head or foot board, showing the manner of fastening'and supporting the end of one of the slats.

Like letters of reference designate corresponding parts in both figures.

My invention consists in the combination of the ordinary slats of a bed-bottom with iron hangers of peculiar construction, guide-bars, coiled springs, and suitable crosspieces, which act as stops and form a support for the parts, arranged substantially as hereinafter described.

In the drawings, A A represent the frame of an ordinary bedstead B B, the head and foot boards; O G, slats, secured together near each end, if desired, by cross-pieces D D, to which they are fastened by screws, or in some other suitable manner. E E are iron hangers of the construction shown, with holes f f in their outer ends for the passage of the guiderods c c, and their inner ends, to which the slats O are secured, being provided with flanges g g, which turn up at the sides to secure vthe slats from lateral displacement.

The slats may be further fastened to the irons by screws or rivets i z'.

The rods c c, of which there is one at each end of every slat, are seemed vertically between two cross-pieces, H H', which are fastened by screws or otherwise to the head and foot boards B B. These cross-beam H H' are of such distance apart as to allow sufficient space for the springs s s, which are coiled around the guides c c under the ends of E. They also serve as stops to limit the vertical motion or play ofthe hangers and form a su pport for the guide-rods, which are thereby retained in their proper relative and upright position. The upper one, H', is secured so as to be easily detached when required for inserting or removing the bed-bottom, which is accomplished by passing the holes fin the ends of irons E over the upper ends of the rods c.

The advantages of my improvement are its economy of construction, durability, and nonliability to get out of order, the facility with which it may be applied to any ordinary bedsteads, and the ease with which any of its parts may be repaired or replaced should they become broken or injured. It also forms a light and easy stretcher, and is admirably adapted for the berths of sleeping-cars and vessels.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the slats O (l, hangers E, guide-rods c c, coiled springs s s, and stops or cross-pieces H H', the whole arranged and operating substantially in the manner and for the purpose set forth.

ALEXANDER COLE.
